Effect of honey addition on fermentation activity ofLactobacillus caseiLc-01 in cow’s and goat’s milk: A kinetic study

Abstract

The aim of this study was to determine the stimulatory effect of honey addition on fermentation activity of Lactobacillus casei Lc-01 in cow’s and goat’s milk. Two monofloral honey types, dark-coloured chestnut and light-coloured acacia honey were added to cow’s and goat’s milk before fermentation. Different mathematical and statistical models were used to describe the kinetics of fermentation in all analysed samples. The basic hypothesis of this study was that addition of honey could influence fermentation kinetics in both types of milk. Comprehensive kinetic analyses suggested complex interaction between all components in fermented milk samples. The results presented in this paper showed that addition of both types of honey had a stimulatory effect on the growth of Lactobacillus casei Lc-01 in cow’s and goat’s milk. Addition of acacia honey significantly stimulated (P<0.05) the growth of Lactobacillus casei Lc-01 in cow’s and goat’s milk. This resulted in higher number of Lactobacillus casei cells, as w...
